Question

Please help me with this concept; I have a Unit Test coming up and I need to nail this.

"Find any points of discontinuity for the rational function."

Answer 1

y= (equation attached)

Answer 2

Originally, I was going to try to cancel out any repeat values so that I could simplify this, but they're all the same! I realize that I need to find two x values, but I'm not sure where to start.

Answer 3

Answer 4

sorry, they're all different, not the same. If they were the same, this problem would be easier.

Answer 5

You have a rational polynomial over another rational polynomial. For discontinuity, you look for where the function is not defined. In this case, it's where either of the denominator factors are zero. Hint: ther are 2 such values for your "x" that gives you discontinuity.

Answer 6

So for the denominator, the values of discontinuity are -9 and -7?

Answer 7

You got it! Good job!

Answer 8

Oh! Thank you so much! I guess I was overanalyzing this whole thing. Thank you for helping me to understand this. :D

Answer 9

Good luck to you in all of your studies and thx for the recognition! @tafkas77

And you're welcome!

Answer 10

You rock. Now I feel confident with this concept. :)

Answer 11

hey, @tafkas77 , before you go I have to say something. Will you stick around?
